From PHP 5.4.5, COM and DOTNET is no longer built into the php core.you have to add COM support in php.ini:
[COM_DOT_NET]
extension=php_com_dotnet.dll
Otherwise you will see this in your error log:
Fatal error: Class \'COM\' not found
The extension is included with php 5.4.5 for Windows.
インストール手順
これらの関数を使うには、php_com_dotnet.dll を php.ini で有効にしておく必要があります。
使いたい COM オブジェクト (MS Word など) は別途インストールしておかないといけません。 そういった COM オブジェクトは PHP にバンドルされていませんし、 そもそもバンドルできません。

As of 5.3.15 (if you are still on 5.3 branch) you have to add extension=php_com_dotnet.dll line into your php.ini to have COM, DOTNET, VARIANT and similar classes available and working.
From PHP Change log:
COM
Fixed bug #62146 com_dotnet cannot be built shared
Because of this, the official PHP builds for Windows are now built with "--enable-com-dotnet=shared" option, which means no COM/DOTNET support by default.
Some of my projects that I currently maintain use adodb library which uses VARIANT class and fails to work without it.
